SuperA Coating

The well established SuperA coating known as AlTiN coating (Aluminum Titanium Nitride coating), has been developed at Guhring. By optimizing the structural, chemical and mechanical properties of the new SuperA coating are an extremely high hot hardness, very good oxidation resistance and excellent coating adhesion have been achieved. This coating is used exclusively on carbide cutting tools and is ideally suited for difficult to machine aerospace materials such as titanium alloys, Inconel as well as machining hardened steel materials (>52 HRC) and HSC applications.
